Start with the application
Different technologies require different materials and purity levels. The relevant question is not simply whether a metal is available, but whether it can be supplied in the form and quality required.
Look beyond extraction
Processing, refining, transport and manufacturing connect a mineral resource to an end product. Constraints at any stage can influence cost and delivery reliability.
Review sourcing evidence
Origin, custody records and supplier information help evaluate a supply chain. Recycling and material efficiency can contribute to resilience, but their role depends on product design and available recovery systems.
